A 4.2-m-diameter merry-go-round is rotating freely with an angular velocity of 0.79 rad/s . Its total moment of inertia is 1790

Nezavi [6.7K]

Answer:

$w_2=0.467rad/s$

Explanation:

Four people standing on the ground each of mass and usually this questions have to find the final angular velocity

$m_t=4*70kg=280kg$

The radius $r=4.2/2=2.1m$

Angular velocity $w_1=0.79rad/s$

The moment of inertia total is $I_t=1790 kg/m^2$

Momento if inertia

$I_1=m_t*r^2$

$I_1=280kg*(2.1m)^2=1234.8kg*m^2$

Angular momentum

$I_1*w_1=I_t*w_2$

Solve to w2

$w_2=\frac{I_1*w_1}{I_t}$

$w_2=\frac{1790kg*m^2*0.79rad/s}{3024.8kg*m^2}$

$w_2=0.467rad/s$

A police siren of frequency fsiren is attached to a vibrating platform. The platform and siren oscillate up and down in simple h

babunello [35]

Answer:

he maximum frequency occurs when the denominator is minimum

f’= f₀ $\frac{343}{343 + v_s}$

Explanation:

This is a doppler effect exercise, where the sound source is moving

f = fo $\frac{v}{v-v)s}$ when the source moves towards the observer

f ’=f_o $\frac{v}{v+v_{sy}}$ Alexandrian source of the observer

the maximum frequency occurs when the denominator is minimum, for both it is the point of maximum approach of the two objects

f’= f₀ $\frac{343}{343 + v_s}$

Two 110 kg bumper cars are moving toward each other in opposite directions. Car A is moving at 8 m/s and Car Z at –10 m/s when t

Marysya12 [62]

From the law of conservation of momentum
m1u1+ m2u2= m1v1+ m2v2
110*8+ 110*-10= 110*-10 + 110* v2
v2= 8 m/sec
